如何用json先生成列表然后列表项再变成字典或json数据？

[mengzhuo]

我竟然看成了……如何用json先生/成列表/然后列表项再变成字典或json数据？

这本身就是个js可读的列表，列表里是object，不明白LZ要干什么

[justfly]

import json
data_list=json.loads("xxxxx")
for data_item_dict in data_list:
# do something

[pc10201]

@justfly

#coding=utf-8
import json
import requests


r=requests.get('http://vip.stock.finance.sina.com.cn/quotes_service/api/json_v2.php/Market_Center.getHQNodeData?page=1&num=10&sort=changepercent&asc=0&node=sz_a&symbol=')
print r.text
data_list=json.loads(r.text)
for data_item_dict in data_list:
print data_item_dict

不行啊，代码报错

这个json不太标准， 比如key没加引号, js处理没问题, 其他语言就看json库是不是兼容非标准了。

你可以拿pyv8封一个函数， 把这个字符窜当object传进去做一个JSON.stringify, 再吐给python的json库解。

[9hills]

这个不符合JSON标准，需要单独处理的。

[Jowei]

你把代码总request.text 改成 request.content 试试？ 我记得requests 返回后，有不同的格式。其中content好像是unicode格式, 再用json.loads()试下。

[pc10201]

@Jowei 也不行

[pc10201]

@Ever 谢谢提醒，我对json还不太熟悉，后来用正则表达式提取出来了~

[stc]

也可以先用正则加上引号，再load
